Trying to make someone buy Bitcoin or any investment is not a good idea. Why? Well, because these things can be pretty tricky. They can make you money, but they can also make you lose it just as fast. Everyone's got different money goals and how much risk they can handle. So, it's better to let people decide on their own when it comes to investing. Give them the facts, let them think it over, and support whatever choice they make without pushing them into it. That way, they can make the right decision for themselves.
First of all, any investment is something that is completely free to be done and chosen by anyone as long as the person who chooses and does it really understands the method and the risks. Apart from that, the investor himself is also very familiar with the asset he has chosen and has also done some research in the past on that asset so that he can be quite comfortable making a decision at this time. So this kind of thing is not a compulsion nor is it a bad idea to do it because it is already based on very wise methods.
Remember, it's their money and their future, so they should have the final say in how they want to handle it.
Those who still want to remind you have also started and are making their own money so you don't need to assume that every carrier of information about Bitcoin and investment is out to take your money. But they could just tell everyone about it by making up their own minds after knowing it, so this is also something to keep in mind before judging other people's information.
